FWIW, MST3K episodes DO air on a weird cable channel that's part of the AT&T U-Verse package (at least in Atlanta). I say a "weird" cable channel because the name is something like ZLive or Channel Z or Z-TV -- when you scroll through the actual channel listings, the abbreviation is "ZLIV" or "ZLIVHD" -- but neither Jeff nor I could find a website for the channel, or any sort of online listings .. and even when that channel does play MST3K it rarely says so; it simply says "Movie." Not "MST3K," not even "Whatever actual movie they're riffing," just ... "movie."

ZLive or ZTV is NOT to be confused with "Zee TV" in India, or something called Z TV which was an early pay-TV station in California, or any other existing Z-list channels which definitely don't correspond to the one that plays MST3K on U-Verse.

Basically he's finding the original cuts of movies (where possible) that were in MST3K episodes and then re-cutting the riff audio on to them. That way you can see what they were originally like while still getting the riffs.
